Listed oil and gas companies on the Nigerian Exchange (NGX) generated a total revenue of N4.9 trillion in the first half of 2025.
This represents a 33.45% increase from the same period in 2024, reflecting stronger sales across the sector and growing market demand.
Revenue, often called “the top line,” is the total money a company earns from selling goods and services before subtracting any costs or expenses.
A solid revenue stream is important because it gives companies the ability to cover costs and still generate profit. It also signals growth and resilience, which can attract investors even when operational challenges exist.
This report focuses on the oil and gas companies that generated the highest revenues in the first half of 2025, placing more emphasis on actual figures than on year-on-year performance.

- Exploration and production of oil and gas contributed N267.5 billion, with the rest from other activities.
